Setup

Project level build.gradle file

maven { url 'https://jitpack.io' }

Include the following dependency in your apps build.gradle file.

implementation 'com.github.pankaj89:SimpleAdapter:3.4.1'

How to use (kotlin)

Create Adapter

val adapter = SimpleAdapter.with<User, ItemBinding>(R.layout.item) { adapterPosition, model, binding ->
    binding.text.text = model.name
}
recyclerView.adapter = adapter

You will get adapter position, model and binding simply bind your model with binding

Add list to adapter

val list = ArrayList<User>()
for (i in 0..100) {
    list.add(User("$i"))
}
adapter2.addAll(list)
adapter2.notifyDataSetChanged()

Add Multiple Views

adapter.addViewType<Item1Binding>(R.layout.item_1, binder = { adapterPosition, model, binding ->
    binding.text1.text = model.name
}, viewTypeLogic = { model ->
    //Return true if received model is your view type
    model.name.toInt() % 5 == 0
})

Here ViewTypeLogic is callback where you need to return true/false based on your type

Add click listener for your views

adapter.setClickableViews({ view, model, adapterPosition ->
    Toast.makeText(this@MyActivity, "${model.name} clicked", Toast.LENGTH_SHORT).show()
}, R.id.text, R.id.text1, R.id.text2)

Load more for pagination

adapter.enableLoadMore(recyclerView) {
    //Call WS here to load more item after items added call setLoadMoreComplete(), If there are more data to load return `true` else `false`
    true
}

• Return true when you need to load more items.
• When subsequent page are added to adapter call setLoadMoreComplete()

Filtering based on you keyword

adapter.performFilter(text = "", filterLogic = { text, model ->
    //Return true if this model is applicable for your filtering
    model.name.contains(text)
})

• Return true when you need to load more items.
